Collector Boosters are a shortcut to the coolest cards in Commander Legendsfill your deck with rares, foils, and special art from the first booster packs created specifically for Commander
These cards are harder to find than usual with them being the second-highest rarity in the set behind Enchanted, but if you are able to get your hands on a playset of these they are great cards to build around
Neither half is excellent, but both halves together is interesting
As you achieve minor weekly quests, such as inflicting X amount of damage or casting X number of spells of a certain color, you earn in-game gold that can be spent on slowly acquiring more booster packs, which you can open to earn a handful of randomly-generated cards
There are a lot of utility lands where the only downside is that they don't need the colored mana other decks require, but colorless decks get to use them for no drawbacks at all
